Blastoid, later known in Japan as  Ponter (, ポンター Pontā ) ? is an enemy that appears in  . It is a mass-produced Sonic the Hedgehog 3 Badnik model created by Dr. Robotnik.
Blastoid resembles miniature version of an artillery bunker. It is a small blue and yellow colored
Badnik with small eyes and cannon, that fires energy projectiles.
The Blastoids are encountered in
Hydrocity Zone. When approached, a Blastoid will fire three projectiles in the player's direction at a 45 degree angle, but it is unable to aim. Blastoids are not much of a threat, but they can catch the player off guard. They are placed at spots such as ledges, where they can be tough to avoid. In underwater sections, lone Blastoids are required to be defeated to make platforms crumble and open lower paths for the player.
Spin Jump defeats Blastoids easily. The projectiles they fire can be deflected by any shield available; the Water Shield, which is common in the Hydrocity Zone, is the best one to use, as almost all Blastoids are located underwater.
The Pokémon franchise has a Pokémon named Blastoise, which is similar to Blastoid. In fact, both are blue, have a large cannon and have some-sort of water-based features.
One of the enemies in , the Sonic Advance 3 Clam, has an identical attack pattern to the Blastoid.
